Seiko Epson · Temperature Compensated Crystal Oscillators (TCXOs) · SMD2016-4P
X1G0054410204 from Seiko Epson, in a SMD2016-4P. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | N.C. (TCXO) | unconnected | Not connected on the TCXO variant; keep it open or connect it to GND, and it does not work as a ground pin. |
| 2 | GND | power_in | Ground terminal at 0 V; the metal cap on top of the device is directly connected to this pin, so no conductor at non-ground potential may touch the cap. |
| 3 | OUT | output | Clipped sine output (10 kΩ // 10 pF load, 0.8 Vpp min.); an external DC-cut capacitor of at least 0.01 µF must be attached because none is included in the TCXO. |
| 4 | VCC | power_in | Supply voltage of 1.7 V to 1.9 V for the 1.8 V variant (absolute maximum VCC-GND -0.5 V to +4.0 V), with a 0.01 µF to 0.1 µF bypass capacitor placed as close to the device as possible. |
